“…Huntington [1] in 1935 and it continues to be on the forefront of scientific inquiry; new predictions include high-T superconductivity [2,3] and novel ordered quantum fluid behavior [4,5]. A significant body of experimental work [6][7][8][9] and advanced numerical simulations [10] have elucidated the properties of hydrogen at high pressure and have provided a great deal of insight to its rich phase diagram [11]. From a practical standpoint, if metastable MH [12] were to be obtained, it could be a revolutionary clean energy source [13].…”

“…Solid MH has not yet been observed under static pressures of up to 342 GPa [14,15]. Dynamic compression beyond 200 GPa has also been employed [9,16]. The only direct evidence so far was the brief observation of a highly conductive liquid phase under a shockwave pressure of 140 GPa and temperatures around 3000 K [17].…”

“…For MH, using [25] µ ∼ 0.1 Ry/atom ∼ 10 11 J/m 3 and σ ∼ 1 Ry/atom (for structurally different phases) yields R 0 ∼ 10 Å and W 0 ∼ µR 3 0 ∼ 10 3 eV. Then with α = 0.1, and [9] ε ∼ 1, we obtain E c ∼ 10 7 V/cm.…”

Electric field induced nucleation is introduced as a possible mechanism to realize a metallic phase of hydrogen. Analytical expressions are derived for the nucleation probabilities of both thermal and quantum nucleation in terms of material parameters, temperature, and the applied field. Our results show that the insulator-metal transition can be driven by an electric field within a reasonable temperature range and at much lower pressures than the current paradigm of P > ∼ 400 GPa. Both static and oscillating fields are considered and practical implementations are discussed.

Abstract. The high Explosive Magnetic Flux Implosion Compression Generator (EMFICG) is a kind of unique high energy density dynamic technique with characters like ultrahigh pressure and low temperature rising and could be suitable as a tool of cylindrical isentropic compression. The Institute of Fluid Physics, Chinese Academy of Engineering Physics (IFP, CAEP) have developed EMFICG technique and realized cylindrical isentropic compression. In the experiments, a seed magnetic field of 5-6 Tesla were built first and compressed by a stainless steel liner which is driven by high explosive. The inner free surface velocity of sample was measured by PDV. The isentropic compression of a copper sample was verified and the isentropic pressure is over 100 GPa. The cylindrical isentropic compression process has been numerical simulated by 1D MHD code and the simulation results were compared with the experiments. Compared with the transitional X-ray flash radiograph measurement, this method will probably promote the data accuracy.
